Re: shadow mask based on shaded relief

Thank you for the replay. Actually i'm working on Erdas 2014, and i can't open the model file you send me.

The shaded relief function gave me a raster file with one layer. based on thersholds, i have got a good delimitaion to shadows in my original image. All i want is to find a way to create a vector to mask shadows in my original image. i'm new with erdas. Is there any simple way to do what this?

Re: shadow mask based on shaded relief

Why create a vector? Just use the shadow pixels to mask out the shadow location. Use the Either/Or operator to apply a mask:

I also strongly recommend upgrading to ERDAS IMAGINE 2018 - as Johnnie says, there's significant new functionality including the much more rigorous Analyze Radiance operator for generating a shadow mask. Newer versions also have the Apply Mask operator

What company do you work for? I can get someone to contact them and get your software upgraded.
